Alpine Electronics of America, Inc. is now shipping the R-A90S 6-Channel Amplifier. The R-A90S joins Alpine鈥檚 R-Series amplifier lineup that鈥檚 matched in both power and performance with the R-Series speakers and subwoofers for a 鈥淟oud and Fun鈥� music experience.
All the Power You Need
Customers have grown to love the 5-channel amplifier solution due to its ability to provide total system power from a single amplifier. To add value and versatility to this category, without sacrificing the subwoofer power of a 5-channel, Alpine created a 6-channel amplifier with staggered power that has double the amount of power on the 5th and 6th channel. This allows the amplifier鈥檚 final two channels to provide a solid 500 watts to a single subwoofer at 4鈩� when in 5-channel mode or 150 watts x 2 at 4鈩� to mid-basses in 6-channel mode.
The R-A90S can be used in various layouts including a powerful 3-channel mode (200W x 2 @ 4鈩�, 500W x 1 @ 4鈩�), a 5-channel mode (75W x 4 @ 4鈩�, 500W x 1 @ 4鈩�), or utilize its onboard bandpass crossovers to independently power a 3-way component system in 6-channel mode (75W x 4 @ 4鈩�, 150W x 4 @ 4鈩�).
The result is the most versatile amplifier in its class, as it can act as both a 5-channel amplifier that can single-handedly power a full system as well as a 6-channel amplifier to power a 3-way active front stage. The unique channel layout is also beneficial to the mobile electronic specialist, as they can rely on one amplifier for multiple applications.
Unrivaled Performance
With the highest output in its category, the R-A90S drives power to the sound system to create a big dynamic music range for the listener while maintaining a proper sound stage between the singers and instruments in the music.鈥�
The amplifier鈥檚 high damping factor (>500) produces crisp and clear notes, especially at low frequencies.鈥疶his amplifier has an extremely low phase shift compared to its competitors, which keeps music focused and accurate for the most enjoyable listening experience.
The result is a powerful sound system that produces accurate sound images with minimal phase shift and internal noise throughout the amplifier鈥檚 Hi-Res compatible frequency response.
System Compatibility
The R-A90S has鈥痠nput capability to add the RUX-KNOB.2 Remote Bass Control Knob (sold separately). The remote bass knob controls the bass in the subwoofer by adjusting the gain on the amplifier for quick bass adjustments when needed.鈥�
The R-A90S is now shipping for $599.95 and will be available at Alpine Authorized retailers or online at www.alpine-usa.com through Crutchfield. Installation options can be found on the Alpine-USA website through the store locator.
